Northland may see heavy rain overnight; flash flood watch for North Shore

Heavy rain is in the forecast for much of the Northland overnight into Wednesday, and a flash flood watch has been issued for the North Shore.

The National Weather Service reports that rainfall of 2 to 4 inches is possible in some locations along the North Shore from Two Harbors to Grand Marais from tonight through Wednesday morning. The flash flood watch for those areas runs through Wednesday afternoon.

Elsewhere in the Northland, no flood watches are in effect as of 8 p.m., but heavy rain - possibly up to 3 inches in spots - may fall overnight and could lead to street flooding in some areas, the Weather Service reported. The exact location of where the heaviest rain will fall is hard to pinpoint, but forecast models Friday afternoon suggested that areas along the Iron Range east toward the North Shore were most likely to see greater rainfall through Wednesday morning.

Thunderstorms will remain possible throughout the day Wednesday, with a chance for some severe storms Wednesday afternoon and evening - mainly south and west of the Twin Ports, with large hail and damaging wind the main threats. Check back to duluthnewstribune.com for weather updates on Wednesday.

Parts of the Northland still are recovering after serious flooding - both flash flooding and longer-term river flooding - in late June. But since that heavy rain fell June 19-20, much of the region has been below normal for rainfall. Through Tuesday afternoon, Duluth had received 0.82 inches of rain in July - 2.26 inches below normal.
